+#
+#  Generate node tree from verbose logfile
+#
+#  HOWTO USE
+#  =========
+#
+#  First of all, you need to recompile modules slideshow and canvas
+#  with VERBOSE=t set in the environment, and debug=t defined at the
+#  build tool command line. Then run your slideshow and redirect stdout
+#  to a file.
+#
+#  Then, call 'nodetree.sh trace-file > tree.ps' to generate a
+#  PostScript file for the AnimationNode tree generated during the show.
+#  Since these easily get pretty huge, use only one page, and try to
+#  limit the slide content (which have effects assigned, that is) to
+#  the bare minimum (to reproduce your bug, or whatever you need this
+#  for).
+#
+#  The generated output will have all nodes color-coded with their state
+#  at the point when the tree was dumped (see colors.sh for the color
+#  codes)
+#
+#  When looking for the mechanics that generate the relevant output,
+#  grep for the DEBUG_NODES_SHOWTREE macros in the slideshow source:
+#  Each such place dumps the current node tree to the trace output. Thus,
+#  if you need to check the tree state at other places or times, just add
+#  a DEBUG_NODES_SHOWTREE
+#
